STOP-CLOCK- FOR CASH-REGISTERS.

SPECIFICATION forming part of Letters Patent No. 468,483, dated February 9, 1892.

Application filed March 2, 1891. Serial No- 383,353. (No model.)

To all whom it may concern.-

Be it known that I, ORWELL O. REEVES, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Stop-Clocks for Cash- Registers, of which the following is a description, reference being had to the accompanying drawings, forming part of this specificaion.

My invention relates to the application of a stop-clock to the casing of a cash-register having a locked lid, in the manner and for the purpose hereinafter described.

In the accompanying drawings, Figure 1 represents a perspective view of a cash-register having a clock applied thereto. Fig. 2 is a front elevation of the clock and lid, the latter partly in section.

The purpose of my invention is to register the time at which the store in which the machine is used opened by the clerk or other employ whose duty it is to open it at the beginning of a days business; and it consists in combining a clock provided with a stop device with the casing or cabinet of a cash-register having a locked lid in such manner that while the device for stopping the clock is accessible from the exterior of the case access to the winding and setting devices (especially the latter) can be obtained only by unlocking and opening the lid. The clerk is required to stop the clock when he first enters the store in the morning, and as he has no access to it for any other purpose it will remain at the point at which it is stopped until the proprietor, who has the key to the lid of the machine, unlocks and opens it and sets and starts the I Inasmuch as it is to the interest to the clerk to stop the clock at the earliest moment after he gets to the store, the proprietor may always have a correct report of the exact hour at which the store is opened. As illustrated in the drawings, the clock A is shown hinged to the side of the lid B, so that it may be swung away from it, as in Fig. 2. When swung against the side of the lid, as in Fig. 1,

it may be secured there by a screw 0, passed outwardly through the side of the lid and engaging a threaded hole in an car a on the base of the clock. The inner end of the screw is provided with a milled thumb-piece, by which it may be turned. The lid B has a look at D, by which it may be held closed. When locked, no access can be had to the thumb-piece of the screw 0 to release the clock and permit it to be swung away from the side of the lid, and consequently no access can be had to the winding and setting devices shown in Fig. 2.

Passed through the top of the cylindrical casing of the clock is a thumb-screw E, whose inner end may bear either directly against one of the wheels of the clock mechanism or against a suitable brake-spring capable of being pressed against such wheel, so that when the screw is screwed inward to its farthest limit it will stop the clock.

Inasmuch as it is only necessary that access to the winding and setting mechanism of the clock be, controlled by the proprietor possessing the key to the lid, it is evident that the clock need not be hinged to the side of the lid, but might be secured to the side of the body of the casing. It will also be understood that it is not necessary that the clock be hinged. to the lid or casing, though I prefer to have it so. It might be rigidly secured to the side of the casing, the latter being provided with an opening through which access could be had to the winding and setting devices upon unlocking and opening the lid.

I am aware that it has heretofore been proposed to combine a stop-clock with the lid of a cash-register for the same general purpose as my invention, but in such proposed combination the clock was located in the interior of the casing of the machine, with the stop device projecting through the casing to the exterior, so that while the clock could be stopped by manipulating such device from the exterior of the machine, the clock was hidden and could only be seen upon unlocking and opening the lid. In my improved construction and arrangement of the parts the clock is hinged upon the exterior of the casing, where it is always visible, but is held against the face of the casing to prevent access to its winding or setting devices, by a retaining device which can be manipulated to release the clock only from the interior of the casing,

so that-access to such winding and setting devices is controlled by the regular lock for the lid of the machine.

Having thus fully described my invention, I claim- In a cash-register having a casing provided with a locked lid B, the combination, with such lid, of the clock A, hinged upon the outer side of the lid or casing, said clock havingits winding and setting devices upon its inner face, whereby access can be had to them only when the clock is swung away from the face of the lid 01' casing, a retaining device, such as the thumb-screw O, accessible only from the inner side of the lid opposite the clock A, said screw extending from the interior of the casing through the side thereof into engage- ORYVELL C. REEVES.
